Flexible Circuits

Due to the miniaturisation trend in electronics, flexible circuits are gaining ground from rigid PCBs. Polyimide, PET, LCP or PEN based flexible circuits are manufactured in roll-to-roll format.

Elcoflex manufactures high volume single and double side flexible circuits. Elcoflex has also patented a copper circuit without polymer substrate. Multilayer circuits can be made using the copper layer and additional conductive polymer layers.

Key features are

  • Web width from 250 mm to 550 mm
  • Minimum line/space 50/50 µm depending on the design and materials
  • Copper layer thickness 18µm and 35µm as standard
  • Various substrates can be used (e.g. PET, PI)
  • Various plating options are available
  • Camera assisted diecutting available for special shapes
  • Camera assisted embossing available
  • Screen printable solder masks and dielectrics available in different colors
  • Coverlay lamination available
